If you're a motorsports fan you've probably come across stories on the efforts Formula One has made to reduce its carbon footprint (KERS anyone?), but you might not have heard about what's being done in the world of NASCAR. Turns out it's pretty intense.

In 2008, NASCAR chairman Brian France got to work on creating a green initiative for the series. It wasn't unveiled until 2009 and it tackled the integration of biofuels, as in the switch to E85, employing alternative energy like the solar array at Pocono Raceway, and recycling. The initiative has a "managing director of green innovation," Dr. Mike Lynch, a website with ways everyone can get involved in making the Earth greener, hybrid pace cars and Miss Sprint Cup in a green race suit.

It's gotten bigger every year, and NASCAR will crank up its promotion with a 30-second spot that ran several times during the STP 400 at the Kansas Speedway. You can watch it below.
